Tests an AI's ability to solve a simple but potentially confusing logic puzzle
Sally (a girl) has 3 brothers. Each brother has 2 sisters. How many sisters does Sally have?
Sally has only one sister.
Thus, Sally has 1 sister.
Let me help solve this word problem step by step.
Let's break it down:
The key insight here is that if each brother has 2 sisters, and we know Sally is one of those sisters, then all brothers must share the same sisters.
Since each brother has 2 sisters total, and we know Sally is one of them, there must be one other sister.
Therefore, Sally has 1 sister.
To verify:
The answer is 1 sister.
This is an interesting logical reasoning problem! Let's work through it step by step.
We know:
The key insight is that Sally herself counts as a sister to her brothers. So when we're told that "each brother has 2 sisters," Sally is one of those sisters.
Since each brother has 2 sisters total, and Sally is one of them, that means each brother has 1 sister besides Sally.
But all brothers share the same sisters (they're all siblings in the same family). So if Sally has 3 brothers, and each brother has the same 2 sisters (Sally and someone else), then Sally has exactly 1 sister.
Therefore, Sally has 1 sister.
To solve this problem, I need to analyze the relationships carefully.
Given:
Since Sally is a girl, she counts as a sister to her brothers. So each of Sally's brothers has Sally as one of their sisters.
If each brother has 2 sisters total, and one of those sisters is Sally, then there must be exactly 1 other sister that all the brothers share.
Therefore, Sally has 1 sister.
Sally has 3 brothers. Each brother has 2 sisters. Since Sally is one sister, there must be one more sister to make the total number of sisters each brother has equal to 2. Therefore, Sally has 1 sister.
Answer: Sally has 1 sister.
Sally has one sister. All of Sally's brothers share the same two sisters: Sally and one other girl.
Here's how to solve this classic riddle:
Since each brother has 2 sisters, and Sally is a sister in the family, those 2 sisters must include Sally and one other sister.
Therefore, Sally has 2 sisters.
First, note that each of Sally’s three brothers has exactly two sisters. One of those sisters is clearly Sally. Since each brother’s two sisters must be the same two girls for all of them, there must be exactly one other sister besides Sally.
Therefore, Sally has 1 sister.
Sally has 1 sister.
Explanation:
Sally's 3 brothers each have 2 sisters. Since Sally is one of the sisters, there must be one other sister in the family. Thus, aside from Sally, there is one more sister.
Sally has 1 sister.
Explanation:
Let's break down the problem:
Let's analyze:
Sally's siblings:
The brothers' sisters:
Who are the possible sisters for each brother?
If Sally is the only girl, then each brother would only have 1 sister (Sally). But the problem says each brother has 2 sisters.
Therefore, there must be another sister besides Sally.
Let's check: Suppose Sally has 1 sister (besides herself). So the siblings are:
Children in the family:
Now, for each brother:
So, Sally has 1 sister.
Final answer:
[ oxed{1} ]
Sally has 1 sister.
Sally has no sisters. She is the only girl in her family, as the problem states that she has 3 brothers and they each have 2 sisters, which refers to Sally herself. Therefore, the number of sisters Sally has is 0.
Answer: Sally has \boxed{1} sister.
Let's break this down step by step. Sally is a girl and has 3 brothers. The problem states that each of these brothers has 2 sisters.
Since Sally herself is one of the sisters (as she is a female sibling to her brothers), there must be one other sister to make the total number of sisters for each brother equal to 2. Therefore, the family consists of 2 girls (Sally and her sister) and 3 boys (Sally's brothers).
From Sally's perspective, the number of sisters she has is the number of other girls in the family besides herself. Since there is 1 other girl, Sally has 1 sister.
Answer: Sally has 1 sister.
Let's break down the problem:
Let's name the siblings:
Now, the key: Each brother has 2 sisters.
Since Sally is one of the sisters, let's see if there are more:
Suppose there is only one girl (Sally) in the family.
Thus, Sally must have one sister (since the brothers must have 2 sisters). Let's call this other sister "Anna".
So the siblings are:
Now, each brother has 2 sisters: Sally and Anna.
So, how many sisters does Sally have?
Final Answer:
Sally has 1 sister.
Sally has 2 sisters.
Here's the reasoning:
Therefore, Sally has 2 sisters in total.
Let's analyze the information:
Since Sally is a girl and one of the sisters, for each brother to have 2 sisters, it means there must be a total of 2 sisters in the family (including Sally).
Therefore:
Answer: Sally has 1 sister.
Sally has exactly one sister. Explanation: the "two sisters" each brother sees are Sally plus one other girl. So there are only two girls in the family – Sally and her one sister.
Let
• S = number of sisters in the family (girls)
• B = number of brothers in the family (boys)
Given
Since Sally herself is one of those 2 sisters, the number of sisters Sally has (other than herself) is
2 – 1 = 1.
Sally has 1 sister.
Sally has exactly one sister. Although there are two sisters in the family (Sally and her sibling), if you ask "How many sisters does Sally have?" the answer is 1.
Here's how to solve this:
So, Sally has 1 sister.
To solve this problem, we need to find the number of sisters Sally has based on the given information.
Given information:
Step 1: Find the total number of sisters the brothers have. Number of sisters each brother has × Number of brothers = Total number of sisters the brothers have 2 × 3 = 6
Step 2: Since Sally is also a sister to her brothers, we need to subtract 1 from the total number of sisters to find the number of sisters Sally has. Total number of sisters the brothers have - 1 (Sally herself) = Number of sisters Sally has 6 - 1 = 5
Therefore, Sally has 5 sisters.
Sally has 2 sisters.
Sally has 1 sister.
Explanation:
Sally has one sister. Since all the brothers share the same sisters, Sally and her sister are the two sisters that each brother has.
Trick question! Sally is a sister herself, and each of her brothers has 2 sisters, but those 2 sisters are the same: Sally and one other sister.
So, Sally has 1 sister.
The answer is 1.
Let's break this down:
So, Sally has 1 sister.
I need to work through this step-by-step.
Given information:
Since Sally is one of the sisters that each brother has, and each brother has 2 sisters total, that means th ere must be exactly 2 sisters in the family.
The 2 sisters are:
Therefore, Sally has 1 sister.
I need to think through this step-by-step.
Given information:
Let me work out how many sisters are in the family total.
If each of Sally's 3 brothers has 2 sisters, and all the brothers are in the same family, then there must be 2 sisters total in the family.
Since Sally is one of those sisters, and there are 2 sisters total, Sally must have 1 sister.
Therefore, Sally has 1 sister.
Sally has 1 sister.
Each of Sally's 3 brothers has 2 sisters, which includes Sally herself and her other sister. Since Sally is one of the sisters, she has only 1 sister.
Based on the details in the riddle, Sally has exactly 1 sister.
If there were more (or fewer) than 2 girls total, the "each brother has 2 sisters" part of the riddle couldn't possibly be true. No other interpretation fits the facts as stated.
Some people misread this type of riddle and try to multiply things (e.g., "3 brothers × 2 sisters each = 6 sisters"), but that's incorrect because it massively overcounts the same sisters. There's no need for math here beyond basic counting of boys vs. girls. The family simply has 3 boys and 2 girls, as explained above.
If this doesn't match what you think the answer is, or if there's more context I'm missing, feel free to reply!
If Sally has 3 brothers and each brother has 2 sisters, it means that Sally is one of the sisters. Therefore, Sally has 1 sister.
If Sally has 3 brothers and each brother has 2 sisters, then Sally must be one of those sisters. Therefore, Sally has 1 sister (herself) plus the other sister that her brothers have, making a total of 1 sister for Sally.
Let's break it down:
Since Sally is one of the sisters, and each brother has 2 sisters, that means there is 1 more sister besides Sally.
Sally has 1 sister.
This is a bit of a trick question! Here's how to solve it:
Therefore, Sally has 1 sister.
This is a classic trick question! Here's how to solve it:
Therefore, Sally has 1 sister.
This is a bit of a trick question! Sally is one of the sisters. Since each of her brothers shares the same sisters, there is only one other sister.
So Sally has 1 sister.
Let's break it down:
Now, think about the brothers' perspective:
Each brother is a sibling to Sally and shares the same siblings.
So, when it says each brother has 2 sisters, those are the girls in the family. Since Sally is one girl, and there are 2 sisters in total from the brothers' point of view, that means there must be one other girl besides Sally.
Therefore, Sally has 1 sister.
I need to work through this step-by-step.
Given information:
Let me think about this carefully:
Since Sally is a girl, she is one of the sisters that each brother has.
If each brother has 2 sisters, and Sally is one of those sisters, then there must be 1 additional sister besides Sally.
Therefore, Sally has 1 sister.
To verify:
Sally has 1 sister.
Sally is a girl with 3 brothers, meaning there are 3 male siblings in the family.
Each brother has 2 sisters, which refers to the total number of female siblings from the perspective of any brother.
Since Sally is one of these sisters, there must be one additional sister.
Therefore, there are 2 girls in total: Sally and one other sister.
From Sally's perspective, the number of sisters she has is the total number of female siblings minus herself.
With 2 girls in total, Sally has (2 - 1 = 1) sister.
This can be verified by considering the family composition:
\boxed{1}
Sally has 3 brothers, meaning there are 3 boys in the family. Each brother has 2 sisters, indicating that there are exactly 2 girls in the family. Since Sally is one of the girls, there must be one additional sister. Therefore, Sally has one sister.
This can be verified by considering the family composition:
From Sally's perspective:
From each brother's perspective:
This satisfies both conditions: Sally has 3 brothers, and each brother has 2 sisters.
If there were only one sister (Sally), then each brother would have only one sister, which contradicts the information that each brother has 2 sisters. If there were three sisters, then each brother would have three sisters, which also contradicts the information that each brother has 2 sisters. Thus, there must be exactly two sisters, meaning Sally has one sister.
\boxed{1}
Sally has 3 brothers, meaning there are 3 boys in the family besides Sally. Each brother has 2 sisters, which means there are 2 girls in the family from the perspective of any brother. Since Sally is one of these girls, there must be one other girl in the family.
Therefore, Sally has one sister.
This can be verified by considering the family composition:
From Sally's perspective:
From the perspective of any brother:
The conditions are satisfied: Sally has 3 brothers, and each brother has 2 sisters. If there were only one girl (Sally), each brother would have only one sister, which contradicts the given information. If there were three girls, each brother would have three sisters, which also contradicts the given information. Thus, there must be exactly two girls in the family.
\boxed{1}
This is a bit of a riddle!
Here's how to figure it out:
So, Sally has 1 sister.
Let's break it down:
Now, since Sally is a girl and she has 3 brothers, those brothers are sharing the same siblings.
The key point: Each brother has 2 sisters.
Since Sally is one of the sisters, and each brother has 2 sisters, that means there must be one other sister besides Sally.
So, total sisters = Sally + 1 other sister = 2 sisters.
Therefore, Sally has 1 sister.
2
Explanation: The three brothers share the same siblings. Each brother has 2 sisters, and one of them is Sally. So there must be exactly 2 girls in the family: Sally plus one other sister. Therefore, Sally has 1 other sister besides herself, which means she has 1 sister? Wait—question asks "How many sisters does Sally have?" Since there are 2 sisters total, and one is Sally, the number of sisters Sally has is 1. Correction: The correct answer is 1.
Sally has 2 sisters.
Reason: “Each brother has 2 sisters.” The brothers are Sally’s 3 brothers. Those brothers’ two sisters must be Sally and one other girl. Therefore, there are 2 girls total among the siblings, so Sally has 1 other sister besides herself. Hence, Sally has 1 sister, but the question asks “How many sisters does Sally have?” Answer: 1.
Correction: The phrasing can be confusing. The correct answer is 1 sister (not 2).
Let me work through this step-by-step.
Sally has 3 brothers.
Each of Sally's brothers has 2 sisters.
Since Sally is a girl, she is one of the sisters that each brother has.
If each brother has 2 sisters total, and Sally is one of them, then there must be 1 other sister besides Sally.
Therefore, Sally has 1 sister.
Sally is one of the two sisters in the family.
Since the family has only two sisters total, Sally has one sister.
Sally has one sister (apart from herself).
Each of her 3 brothers has exactly two sisters. Since the brothers share the same sisters, there are only two sisters in total—the two sisters are Sally and her one sister. Hence, Sally has one sister.
1
Explanation: The three brothers share the same two sisters (Sally and one other girl). Counting sisters for Sally excludes herself, so she has one sister.
1
Explanation: If each brother has 2 sisters, there are exactly 2 sisters in the family. Since Sally is one of the sisters, she has 2 − 1 = 1 sister.
1
Reason: If each of the 3 brothers has 2 sisters, there are exactly 2 girls in the family. One is Sally, so she has 1 sister.
Alright, let's tackle this problem step by step. The question is:
Sally (a girl) has 3 brothers. Each brother has 2 sisters. How many sisters does Sally have?
At first glance, it seems straightforward, but let's break it down to ensure we understand it correctly.
Sally's Brothers: We're told that Sally has 3 brothers. So, in the family, there are Sally and her 3 brothers. That's 1 girl (Sally) + 3 boys = 4 children so far.
Each Brother's Sisters: Now, it's stated that each brother has 2 sisters. This is where we need to be careful. Who are these sisters?
Let's list out the siblings based on the information:
Now, for each brother, they have 2 sisters. We know one sister is Sally. So, where does the other sister come from?
This implies there must be another girl in the family besides Sally. Let's call this other sister "Anna" for clarity.
So now, the siblings are:
Now, let's verify:
This checks out.
Now, the question asks: How many sisters does Sally have?
From our list:
So, Sally has 1 sister (Anna).
Wait a minute, but earlier we thought there are two sisters (Sally and Anna). But the question is about how many sisters Sally has, not how many sisters there are in total.
Sally is a girl, and Anna is another girl. So, from Sally's perspective, her sister is Anna. She doesn't count herself when counting her sisters.
Let me rephrase to ensure clarity:
For any brother:
For Sally:
Therefore, Sally has 1 sister.
Initially, one might think that since each brother has 2 sisters, and one is Sally, the other must be another sister, leading to the conclusion that there are 2 sisters in total (Sally and one more). Then, when asked how many sisters Sally has, one might mistakenly say 2, counting both Sally and the other sister. But that would be incorrect because Sally cannot be her own sister.
The correct interpretation is that the "2 sisters" each brother has are Sally and one other sister (let's say Anna). Therefore, Sally's sisters are just Anna, making it 1 sister.
After carefully analyzing the information:
Sally has 1 sister.
Let's analyze the problem step by step:
Now, from the perspective of one brother:
Therefore, the family has:
So, Sally has 1 sister (the other girl) and 3 brothers.
Thus, Sally has 1 sister.
Final Answer: [ \boxed{1} ]
Sally has 1 sister.
Sally is a girl with 3 brothers. Each of those 3 brothers has 2 sisters (including Sally). This means there are 2 girls total in the family (Sally and 1 other sister), and 3 boys total. Sally has 1 sister. The brothers are the same for everyone—Sally herself has 3 brothers.
1
Sally has 1 sister. The family consists of 3 brothers and 2 sisters (Sally and one other). Each brother thus has 2 sisters, which matches the given information.
To determine how many sisters Sally has, let's carefully analyze the information provided:
This means that from the perspective of each brother, there are 2 female siblings in the family — which includes Sally and one more sister.
Since each brother has 2 sisters, and Sally is one of them, the other sister must be another girl in the family.
Thus, the family has 2 girls in total:
Sally is one of the two girls. Therefore, she has 1 sister (the other girl).
$$ \boxed{1} $$
Let's break it down:
Since Sally is one of those sisters, and the brothers each have 2 sisters, that means there must be 2 girls in total: Sally and one more sister.
Sally has 1 sister.
Sally has 1 sister.
The family has 1 girl (Sally) and 3 boys (her brothers), making a total of 4 children. Each of the 3 brothers has 2 sisters (Sally and one other girl in the family). Therefore, Sally has 1 sister.
1
The reasoning starts by establishing the family structure based on the given information. Sally, as a girl, has 3 brothers, indicating at least 4 children in the family: Sally and her 3 brothers.
Next, the statement that each brother has 2 sisters is analyzed. Since Sally is one sister to each brother, an additional sister is required to account for the second sister per brother.
This leads to a total of 5 children: Sally, 1 other sister, and 3 brothers. In this configuration, each brother has exactly 2 sisters (Sally and the other sister).
From Sally's viewpoint, she has 3 brothers and shares the family with 1 other sister, confirming she has 1 sister. This structure satisfies all conditions without requiring additional siblings.
Let’s break it down step by step.
We’re told:
Sally (a girl) has 3 brothers.
So, there are 3 boys in the family, and Sally is a girl — so at least one girl.
Each brother has 2 sisters.
That means, from the perspective of each of the 3 brothers, there are 2 sisters.
Who are those sisters?
Well, Sally is definitely one of them.
Since each brother has 2 sisters, there must be one more girl besides Sally.
So, the sisters are: Sally and one other girl.
Therefore, Sally has 1 sister.
✅ Final Answer: 1 sister
(Sally + 1 other girl = 2 sisters total, which matches what each brother sees.)
To determine how many sisters Sally has, let's analyze the family structure step by step.
Each of Sally’s 3 brothers has 2 sisters. Since Sally is one of those sisters (she's a girl), that implies:
$$ \boxed{1} $$
Let's break this down step by step:
Now, the key is to realize that all the brothers share the same siblings.
So, when it says each brother has 2 sisters, those sisters are the same for all brothers.
Sally is one of those sisters. So who is the other sister?
Since each brother has 2 sisters, and Sally is one, there must be one more sister.
Therefore, Sally has 1 sister.
(Note: From Sally’s perspective, she has 3 brothers and 1 sister — the other girl.)
✅ Answer: Sally has 1 sister.
We are told:
We need to find: How many sisters does Sally have?
Let’s think carefully.
Sally is a girl, and she has 3 brothers. So the family has at least Sally + 3 brothers = 4 children so far.
Now, each brother has 2 sisters.
Who are those 2 sisters?
One of them is Sally. The other must be another girl — because if each brother has only 2 sisters, and Sally is one, then there must be one more sister.
So total sisters = Sally + 1 other girl = 2 sisters.
Therefore, Sally has 1 sister.
Wait — let’s check this again.
If there are 2 sisters total in the family, and Sally is one of them, then she has 1 sister.
And each brother has 2 sisters: Sally and the other girl. That matches.
So:
✅ So the answer is: 1 sister.
Answer: Sally has 1 sister.
To solve this problem, let's carefully analyze the relationships described.
So, if each brother has 2 sisters, then there are 2 girls in total in the family.
$$ \boxed{1} $$
Sally has 1 sister.
Explanation:
1
Explanation: Each brother’s two sisters are Sally plus one other girl. So there are 2 sisters total, meaning Sally has 1 sister.
Sally has 1 sister.
I need to figure out how many sisters Sally has.
Let me break this down step by step:
Since Sally is one of the girls in the family, and each brother has 2 sisters, this means there are 2 sisters total that the brothers count.
One of those sisters is Sally herself, so there must be 1 additional sister.
Therefore, Sally has 1 sister.
To verify: Sally + 1 sister = 2 sisters total, and each of the 3 brothers correctly has 2 sisters (Sally and her sister).
Let me work through this step by step.
Given information:
Let me think about who the sisters are:
So the two sisters are:
Therefore, Sally has 1 sister.
Sally has 1 sister.
Here's how to solve that:
If a brother has 2 sisters, those sisters must be:
Therefore, Sally has 1 sister.
Here's how to solve this:
Answer: Sally has 1 sister.
Let's go step by step.
Step 1: Identify Sally's family from her point of view
Sally is a girl.
She has 3 brothers.
So there are 3 boys in the family and Sally (1 girl so far).
Step 2: Consider the statement "Each brother has 2 sisters"
From a brother's perspective, his sisters are all the girls in the family except himself (since he’s a boy).
If each brother has 2 sisters, that means there are 2 girls in the family total, from the brother’s point of view.
Step 3: Determine the number of girls
We already know Sally is one of these girls.
If there are 2 girls total, then Sally has 1 sister.
Step 4: Conclusion
Sally has 1 sister.
[ \boxed{1} ]
I need to figure out how many sisters Sally has.
Given information:
Now, each brother has 2 sisters.
If each of Sally's brothers has 2 sisters, and Sally is one of those sisters, then there must be one more sister besides Sally.
Let me verify:
Therefore, Sally has 1 sister.
Sally has 1 sister.
Here's why:
The family is made up of 3 brothers and 2 sisters. Sally is one of those sisters. The other sister is also a sister to all three brothers.
Sally has 1 sister.
Here's why:
To determine how many sisters Sally has, we start by analyzing the information provided in the question:
"Sally (a girl) has 3 brothers. Each brother has 2 sisters. How many sisters does Sally have?"
This tells us that from the perspective of each brother, there are 2 female siblings in the family.
So, the family consists of:
The question is: "How many sisters does Sally have?"
Thus, Sally has 1 sister.
$$ \boxed{1} $$
Sally has 3 brothers, meaning there are 3 boys in the family.
Each brother has 2 sisters. Since the brothers' sisters are the girls in the family, and one of them is Sally, there must be one other sister to make it 2 sisters per brother.
Therefore, there are 2 girls in total: Sally and one other sister.
From Sally's perspective, she has 1 sister (the other girl).
Answer: 1
To determine how many sisters Sally has, we can break down the information given in the problem step by step.
Let's denote the sisters as follows:
Since each brother has 2 sisters and Sally is one of them, the other sister must be ( S ). This means that Sally and ( S ) are the only two sisters.
Thus, Sally has 1 sister.
The answer is (\boxed{1}).
Let’s break down the family structure:
Since Sally is already a girl, she counts as one sister. For each brother to have 2 sisters, there must be another girl besides Sally in the family. If there were more than 2 sisters, each brother would have more than 2 sisters.
So, Sally has 1 sister.
Sally has 1 sister.
Sally has 1 sister.
Here's why:
So the family consists of:
Each brother’s 2 sisters are:
So there are 2 sisters in total. Since one is Sally, she has 1 sister.
Sally has 2 sisters.
Here's the reasoning:
Sally is one of the sisters. Since each of her 3 brothers has 2 sisters, that means in total there are 2 sisters for each brother. Since Sally is one of them, the other sister must be another girl.
Each brother has 2 sisters. One of them is Sally herself, so there must be exactly one other girl.
So Sally has 1 sister.

Sally has 1 sister.
Sally has 1 sister.
Sally has 1 sister.
Here's the breakdown:
Family totals: 2 sisters + 3 brothers = 5 children. Each brother sees both sisters, which fits perfectly.
1
Sally has 3 brothers and shares the family with one other sister (making 2 girls total). Each of those brothers therefore has exactly 2 sisters, which fits the details perfectly.
Sally has 1 sister.
Here is the breakdown:
1
Sally and her family consist of 2 girls (Sally + 1 sister) and 3 boys. Each brother has both girls as sisters (2 sisters total), which matches the given info. Sally thus has 1 sister.
I need to figure out how many sisters Sally has.
Let me work through this step-by-step.
Given information:
Key insight: Sally's brothers are also Sally's siblings, so they share the same sisters. When we're told "each brother has 2 sisters," those sisters include Sally herself.
Working it out: If each brother has 2 sisters, and Sally is one of those sisters, then there must be 2 sisters total in the family (Sally + 1 other sister).
Answer: Sally has 1 sister.
Alright, let's tackle this problem step by step. The question is:
"Sally (a girl) has 3 brothers. Each brother has 2 sisters. How many sisters does Sally have?"
At first glance, it might seem a bit confusing, but let's break it down to understand it better.
We have a family with several children, and we're given information about Sally and her brothers. Here's what we know:
We need to determine: How many sisters does Sally have?
First, let's list out the children in the family based on the information given.
So far, we have:
Now, the next piece of information is: "Each brother has 2 sisters."
This means that if we take any one of the brothers, he has 2 sisters.
Let's think about what "each brother has 2 sisters" implies.
Now, who are these sisters? They are the female children in the family.
We already know that Sally is one sister. If each brother has 2 sisters, and Sally is one of them, who is the other sister?
This suggests that there must be another girl in the family besides Sally to make the count of sisters equal to 2 for each brother.
Let's denote the other sister as "Sister 2."
Now, the family looks like:
Now, let's check if this satisfies the condition that each brother has 2 sisters.
Now, the question is asking: How many sisters does Sally have?
From our current family setup:
So, Sally has one sister (Sister 2).
But wait, let's double-check to ensure we haven't missed anything.
Initially, we thought:
But is it possible that Sally is the only sister, and the count is somehow different?
Let's explore that.
If Sally is the only sister:
Then, each brother would have only 1 sister (Sally), but the problem states that each brother has 2 sisters. This doesn't match, so Sally cannot be the only sister.
Therefore, there must be at least one more sister besides Sally to make the count of sisters equal to 2 for each brother.
Could there be more than one other sister? Let's see.
If there are two other sisters besides Sally (let's call them Sister 2 and Sister 3), then:
Now, each brother would have 3 sisters, but the problem says each brother has 2 sisters. This is too many, so we can't have more than one other sister.
Therefore, the only possibility is:
This gives each brother exactly 2 sisters (Sally and Sister 2), which matches the given information.
Now, the question is: How many sisters does Sally have?
Sally's siblings are:
So, Sally has 1 sister.
Initially, one might think that since each brother has 2 sisters, and there are 3 brothers, there are 6 sister instances (3 brothers × 2 sisters each), leading to the idea that there are 6 sisters. But this would be incorrect because all brothers share the same sisters; the sisters aren't unique to each brother.
Another possible confusion is thinking that Sally is not included in the count of sisters for the brothers, leading to an incorrect addition. But Sally is indeed one of the sisters that the brothers have.
After carefully analyzing the family structure and ensuring that all given conditions are met, we conclude that:
Sally has 1 sister.
Sally has 3 brothers. Each brother has 2 sisters. Since Sally is one of the sisters, there must be one more sister to make the total number of sisters each brother has equal to 2. Therefore, Sally has 1 sister.
[ \boxed{1} ]
Sally has 3 brothers, meaning there are 3 boys in the family. Each brother has 2 sisters, meaning there are 2 girls in the family. Since Sally is one of the girls, there must be one other girl. Therefore, Sally has 1 sister.
This can be verified by considering the family structure:
If there were only 1 girl (Sally), each brother would have only 1 sister, contradicting the statement that each has 2 sisters. If there were 3 girls, each brother would have 3 sisters, also contradicting the statement. Thus, exactly 2 girls is the only consistent scenario.
Therefore, Sally has 1 sister.
\boxed{1}
Alright, let's tackle the problem step by step to ensure we understand it fully and arrive at the correct answer.
Problem Statement: Sally (a girl) has 3 brothers. Each brother has 2 sisters. How many sisters does Sally have?
Understanding the Problem: We need to determine the number of sisters Sally has, given the information about her brothers and their sisters.
Breaking It Down:
Sally's Brothers:
Brothers' Sisters:
Key Point to Note: When it's mentioned that each brother has 2 sisters, it's important to recognize that Sally herself is one of those sisters.
Let's Visualize the Family:
Since Sally is one of the sisters, the total number of sisters includes her and possibly others.
Calculating the Number of Sisters:
Each of the 3 brothers has 2 sisters. Since Sally is one sister common to all brothers, we can determine how many additional sisters there are.
Let's denote:
But we know that Sally is one of those sisters. Therefore:
Total sisters = Sally + (Number of additional sisters)
Given that each brother has 2 sisters, and Sally is one of them, there must be one more sister.
So, Total sisters = 1 (Sally) + 1 (additional sister) = 2 sisters
Verification:
Let's verify this to ensure accuracy.
This aligns with our calculation.
Common Pitfall:
A common mistake might be to think that since each brother has 2 sisters, and there are 3 brothers, there are 3 x 2 = 6 sisters. However, this overlooks the fact that Sally is the same sister for all brothers, so we're not adding unique sisters with each brother.
Conclusion:
After carefully analyzing the relationships and ensuring we account for Sally being one of the sisters, we conclude that Sally has 1 sister besides herself.
Final Answer: Sally has 1 sister.
Let's break down the problem step by step to find out how many sisters Sally has.
Problem Statement: Sally has 3 brothers. Each brother has 2 sisters. How many sisters does Sally have?
Understanding the Relationships:
Sally's Brothers:
Brothers' Sisters:
Analyzing the Information:
Since Sally is a girl, she is one of the sisters that her brothers have.
Let's denote the number of sisters Sally has as S.
Setting Up the Equation:
Total sisters that each brother has = Number of sisters Sally has (S) + Sally herself.
However, since Sally is included in the count of sisters, we need to ensure we don't double-count her.
Calculating the Number of Sisters:
From Sally's Perspective:
From Each Brother's Perspective:
Relating Both Perspectives:
The number of sisters each brother has (which is 2) should be equal to the number of sisters Sally has (S) plus Sally herself.
Therefore:
[ S + 1 = 2 ]
Here, S + 1 accounts for Sally and her sisters.
Solving for S:
[ S + 1 = 2 \ S = 2 - 1 \ S = 1 ]
Conclusion:
Sally has 1 sister.
Verification:
Sally has 3 brothers.
Each brother has 2 sisters: Sally and her 1 sister.
This satisfies the condition that each brother has 2 sisters.
Final Answer:
Sally has 1 sister.
Alright, let's tackle this problem step by step. The question is:
"Sally (a girl) has 3 brothers. Each brother has 2 sisters. How many sisters does Sally have?"
At first glance, it might seem a bit confusing, but let's break it down to understand it better.
We have a family with several children, including Sally and her brothers and sisters. Here's what we know:
We need to determine how many sisters Sally has.
First, let's list out the siblings based on the information given.
Now, the next piece of information is that "each brother has 2 sisters."
This means that if you pick any one of the 3 brothers, that brother has 2 sisters.
Here's where it might get a bit tricky. We know Sally is one sister, but are there more?
Let's think about what "each brother has 2 sisters" implies.
If a brother has 2 sisters, those sisters must include Sally and possibly another girl.
But wait—Sally is already one sister. So, if a brother has 2 sisters, and one is Sally, who is the other one?
This suggests that there must be at least one more sister besides Sally to make the count of sisters equal to 2 for each brother.
Let's test this:
Suppose there is only Sally as the sister. Then each brother would have only 1 sister (Sally), but the problem states each has 2 sisters. So, this can't be the case.
Therefore, there must be another sister besides Sally.
So, the sisters are:
Now, let's check if this satisfies the condition that each brother has 2 sisters.
Each brother's sisters would be:
That's 2 sisters, which matches the given information.
Now, the question is asking: How many sisters does Sally have?
We've established that the sisters in the family are:
But the question is about Sally's sisters, not including herself.
So, Sally's sisters are:
That's 1 sister.
Wait a minute, but earlier we thought there are 2 sisters in total (Sally and Emily), but Sally's sisters would be just Emily, making it 1 sister.
But let's double-check the initial interpretation to ensure we didn't make a mistake.
The confusion might arise from how we're counting the sisters.
Total sisters in the family:
Total brothers: 3
Now, "each brother has 2 sisters." Each brother's sisters are Sally and Emily, which is 2. This checks out.
Now, how many sisters does Sally have?
Sally's sisters are the other girls in the family besides herself, which is Emily. So, Sally has 1 sister.
But let me think if there could be more sisters.
Suppose there are 3 sisters: Sally, Emily, and another girl (let's say, Anna).
Then each brother would have 3 sisters (Sally, Emily, Anna), but the problem says each has 2 sisters. So, this can't be.
Therefore, the only possibility is that there are 2 sisters in total: Sally and Emily.
Thus, Sally has 1 sister.
Initially, one might think that since each brother has 2 sisters, and there are 3 brothers, there are 6 sister instances (3 brothers × 2 sisters each), leading to more sisters. But this would be incorrect because all brothers share the same sisters; the sisters aren't unique to each brother.
For example, if there are 2 sisters, each of the 3 brothers has those 2 sisters, totaling 6 sister instances (3 brothers × 2 sisters), but the actual number of sisters is just 2.
Let's confirm with the numbers:
Each brother's sisters: Sally and Emily (2 sisters) — matches the given information.
Sally's sisters: Emily (1 sister)
Therefore, Sally has 1 sister.
After carefully analyzing the problem and considering the relationships, the correct answer is:
Sally has 1 sister.
To determine how many sisters Sally has, let's analyze the information step by step:
Sally is a girl, and she has 3 brothers.
This means there are 3 boys in the family (her brothers).
Each brother has 2 sisters.
From the perspective of any one brother, he sees 2 girls in the family.
Since Sally is one of the girls, there must be one more girl besides Sally to make up the 2 sisters each brother counts.
Total number of girls in the family:
How many sisters does Sally have?
Sally herself is one of the girls, so the number of sisters she has is the other girl(s).
Since there are 2 girls total and Sally is one, she has 1 sister.
Answer: Sally has 1 sister.
If each of the three boys has exactly two sisters, there are two girls in the family. Sally is one of them, so she has one sister.
Alright, let's tackle this problem step by step. I'll start by understanding the information given and then try to visualize the family structure to find out how many sisters Sally has.
We have the following information:
The question is: How many sisters does Sally have?
At first glance, it might seem straightforward, but let's break it down to ensure we don't miss anything.
First, let's list out the family members based on the information:
So far, the family consists of:
Now, the next piece of information is that each brother has 2 sisters.
This is where we need to be careful. The statement says that each of Sally's brothers has 2 sisters.
Let's think about what this means for one brother, say Brother A:
Who could these sisters be?
We already know that Sally is a sister to Brother A because Sally is a girl and Brother A is her brother. So, one of Brother A's sisters is Sally.
But the statement says Brother A has 2 sisters, not just one. So, there must be another sister besides Sally.
This implies that there is another girl in the family who is a sister to Brother A.
Similarly, this would apply to Brother B and Brother C as well. Each of them has 2 sisters: one is Sally, and the other is this additional sister.
From the above, we can deduce that there is another sister besides Sally.
Let's name this additional sister: Sister X.
Now, let's list all the siblings:
Now, let's verify the condition that each brother has 2 sisters:
This checks out.
Now, the question is: How many sisters does Sally have?
From our list:
Out of these, the sisters are Sister X.
So, Sally has 1 sister: Sister X.
Let me double-check to ensure this makes sense.
Now, for each brother:
This matches the given information that each brother has 2 sisters.
Now, for Sally:
Therefore, Sally has 1 sister.
Initially, one might think that since each brother has 2 sisters, and there are 3 brothers, the total number of sisters is 2 (as each brother's sisters are the same two girls).
But the key is to realize that Sally is one of those sisters, and the other sister is someone else.
Another way to look at it is:
After carefully analyzing the relationships and verifying the counts, it's clear that:
Sally has 1 sister.
Answer: 1 sister.
Why:
The brothers each have 2 sisters total. One of those sisters is Sally herself, so there is one other girl. Therefore, Sally has one sister.
Each brother has 2 sisters, and one of those sisters is Sally. So there are 2 sisters total in the family.
Therefore, Sally has 1 sister.
All 3 brothers share the same sisters. Since each brother has 2 sisters, the family has 2 girls total. One is Sally, so the other is Sally’s one sister.
Answer: 1 sister.
